No.
When I sort the triggers I get:
test=# create table trg_str(fld_1 varchar);
CREATE TABLE
test=# insert into trg_str values ('trigger_1_update_fts'),
('trigger_2'), ('trigger_3'), ('trigger_1_check_nocycle');
INSERT 0 4
test=# select * from trg_test order by fld_1 ;
id | fld_1
----+-------
(0 rows)
test=# select * from trg_str order by fld_1 ;
fld_1
-------------------------
trigger_1_check_nocycle
trigger_1_update_fts
trigger_2
trigger_3
Is this how you want them to fire as it does not match what you say
above?:
(I know they were not /declared/ in that order, but..)
Yes, all "trigger_1_*" are the "actuall triggers triggering the logic",
trigger_2 and trigger_3 are only there as part of the "make
constraint-triggers fire only once"-mechanism, in which the function in
the first trigger is the function performing the actual logic.
So, being I want 2 "logical chunks" to happen I have two
"trigger_1"-triggers (there is no established terminilogy for this
AFAIK), each calling a function performing the logick which is to happen
only once (per row).
"The first "main" trigger-function is update_company_fts_tf() ... The
second "main" trigger-function is company_parent_no_cycle()"
It might be easier to understand if sketch out a schematic version of
what you are trying to achieve.
The point is; I want to functions to be called
- update_company_fts_tf()
- company_parent_no_cycle()
, each only once, as constraint-triggers on the same table. So they are
called by the "level 1 triggers" which must fire first.
To be clear the order they fire relative to each other is not important?
Is it clearer now what I'm trying to achieve?
Sort of, though I am still not entirely what the whole process is trying
to achieve. What the mix of deferred and un-deferred triggers and
'logical' and housekeeping functions are doing is not clear to me. That
is why I suggested a schematic representation of the trigger flow would
be helpful. Leave out the fine details and create a flow chart of what
you want to happen.
